What's an example of Customer Match driving personalised, high-performance campaigns?

Customer Match leverages your first-party data (like email lists) to re-engage existing customers or find new ones with similar profiles. The most effective use is to identify and target your most loyal customers with tailored offers, as this directly drives sales by capitalizing on existing relationships and purchase history. The other options are less accurate or describe less optimal uses: Reaching users who haven't shown interest and don't want to be targeted is ineffective and goes against privacy best practices. While Customer Match can help expand your audience, simply targeting users who haven't interacted with your website with personalized messaging isn't its primary or most impactful use for "high-performance" campaigns; it's more about leveraging known customer data. Customer Match uses your first-party data, not "maximising uploaded third-party data," which is a distinct concept.
